actually the better version of the "snow moc" which doesnt really exitst is the Snow Clog by
Solomon which is made for runing around after skiing....they are totally water proof and comfortably....no laces and great year round.
merrell makes the Jugle Moc... prety much a heavy slipper. made with water resitant suede. alot lett comfortable then the snow clog but cheaper. they do make a water prook alpine moc and a water prook winter moc with gortex but they are pricey.
there is always the rubber birki clog by berkinstock or you can get the professional clog by dansko.....these guys are super suportive and long lasting.
hope this helps.
